Supports Iframe

A simple API to check if a URL can be loaded inside an iframe.

How it works?

Takes a URL like: http://localhost:8000/api?url={URL}

Example: http://localhost:8000/api??url=https://example.com

And checks if the URL follow those rules:

• response status must be a 2xx
• response headers does not contain x-frame-options set to SAMEORIGIN nor DENY

You can try it there:

• not a 2xx: https://supports-iframe.vercel.app/api?url=https://column-view.com/404
• can be loaded: https://supports-iframe.vercel.app/api?url=https://monitoror.com
• cannot be loaded: https://supports-iframe.vercel.app/api?url=https://google.com
